Abstract: Methods and systems for backing up and restoring different point in time versions of a virtual machine, a real machine, an application, a database, or a set of electronic files using a plurality of independently managed snapshot chains are described. The different point in time versions of the data being backed-up may be stored using two or more snapshot chains corresponding with two or more data partitions of the data being backed-up. Over time, additional full image snapshots may be acquired from an external server or generated locally by a storage appliance to limit the snapshot chain lengths and to limit the aggregate block chain lengths for the snapshot chains. Acquisition and generation of the additional full image snapshots may be staggered across different data partitions to limit computational and storage costs per snapshot.

Abstract: A data management and storage (DMS) cluster of peer DMS nodes manages data of a compute infrastructure by generating snapshots of partitions of a fileset of the compute infrastructure and providing a passthrough for storing the snapshots in a data storage separate from the DMS cluster, such as a cloud computing system. In one approach, the DMS nodes determine partitions of a fileset using fileset metadata, generates snapshots of the partitions, and stores the snapshots in the data storage. Each DMS node may include a local storage which is used to facilitate creation of a snapshot of a partition. The snapshot may be removed from the local storage after being sent to the data storage. Rather than storing the snapshot, the DMS cluster stores fileset metadata that is referenced to retrieve the snapshot from the data storage. The snapshot is deployed to retrieve a file stored in the partition.
